Abstract
An apparatus is provided for remote selective operator adjustment and display of the position of adjustment of a plurality of ground-supported planting units of a planter. The apparatus includes a planter gauge wheel on each unit adjustably mounted thereto and supporting each unit over the ground. A position sensor on each unit conveys gauge wheel adjustment information for numerical display on a central control box mounted adjacent to the planter operator'"'"'s position. A hydraulic or electric cylinder mounted on each unit selectively effects positional adjustment of the respective gauge wheel according to operator control signals. The units are controlled in one embodiment via individual planter unit switches or a single planter adjustment switch manipulated by the operator. In other embodiments the units are controlled via microprocessor control systems wherein operator commands are entered via a keyboard or a rotary switch. The positional display of each planter unit assists the operator in making the remote planter unit adjustments.
